Which CG position generally decreases lateral stability and makes the aircraft less resistant to stall characteristics?

Explanation:
Moving the center of gravity toward the tail lowers the aircraft’s ability to resist rolling disturbances. The weight farther aft reduces the effectiveness of the dihedral/pendulum effect that helps keep the wings level after a disturbance, so lateral stability decreases. It also makes the aircraft more sensitive in high-angle-of-attack attitudes; elevator authority to recover from a stall is reduced, so stall resistance is worsened and stall behavior can become more abrupt. For these reasons, a rearward CG is the position that generally decreases lateral stability and makes stall characteristics less favorable.
